Study: Complete Removal of Added Sugar from Diet Worsened Mouse Health
Scientists in Kuwait found that eliminating sucrose from a low-fat diet in mice led to metabolic disturbances and gut inflammation, suggesting that dietary extremes can be risky.
Although experts have long promoted the idea that cutting added sugar is key to good health, a new experiment on mice indicates that such a radical approach may not always be beneficial. Researchers at the Dasman Diabetes Institute in Kuwait monitored the health of lab mice for 16 weeks. They compared two groups of rodents: one group had sucrose removed from a low-fat diet, while the other continued to consume it.
Body weight did not differ between the groups, but analyses revealed several concerning changes. In the mice without sucrose, beneficial gut bacteria decreased, while inflammation-promoting microbes increased. Their livers accumulated more fat, and signs of insulin resistance—often linked to type 2 diabetes—appeared. Blood sugar control also worsened.
The scientists concluded that removing sucrose from a low-fat diet strongly disrupts the gut microbiota and creates an imbalance. This imbalance triggers inflammatory processes in both the gut and liver, ultimately disturbing the body's metabolic rhythm. The study serves as a reminder that dietary extremes can be risky; even completely eliminating a commonly vilified substance like sugar can upset the finely tuned mechanisms of the body. How applicable these findings are to humans remains to be determined in further research. The results were published in the journal "Frontiers in Immunology."
